SOAP 1.2 yields bad request while SOAP 1.1 works

web-services

I have created an ASP.NET webservice (asmx) to allow 3rd party software to connect to my solution. The webservice works well when called using SOAP 1.1 or via ASP.NET's invocation form when called from the server on which it resides.

So what's the problem, the connecting party only supports SOAP 1.2, when calling the webservice using SOAP 1.2 it returns 400 Bad request.

I have enabled SOAP 1.2 in the web.config:

<configuration>
    <system.web>
        <webServices>
            <soapExtensionTypes>
                <add type="Microsoft.Web.Services2.WebServicesExtension, Microsoft.Web.Services2, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" priority="1" group="0" />
            </soapExtensionTypes>
            <protocols>
                <add name="HttpSoap12" />
                <add name="HttpGet" />
                <add name="HttpPost" />
            </protocols>
        </webServices>
    </system.web>
</configuration>

I use the extension for another part, I've tried to disable it through location-specific configuration but that did not yield any results.

I have enabled tracing:

<system.diagnostics>
    <trace autoflush="true" />
    <sources>
        <source name="System.Web.Services.Asmx">
            <listeners>
                <add name="AsmxTraceFile" type="System.Diagnostics.TextWriterTraceListener" initializeData="D:\Trace.log" traceOutputOptions="LogicalOperationStack, DateTime, Timestamp, ProcessId, ThreadId" />
            </listeners>
        </source>
    </sources>
    <switches>
        <add name="System.Web.Services.Asmx" value="Verbose"  />
    </switches>
</system.diagnostics>

Using the Chrome Advanced Rest Client I send the following request:

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <authenticateUser xmlns="http://services.kvh.nl/foo">
      <username>kvh</username>
      <password></password>
    </authenticateUser>
  </soap12:Body>
</soap12:Envelope>

Which results in a 400 Bad Request and the following entry in the trace log:

I've googled to near insanity but unfortunately I haven't been able to find a solution.

Any help is very much appreciated.

EDIT:

Unfortunately rAhuID's suggestion te remove SOAP 1.1 support this did not solve the problem. I went on and tried a bit more option such as clearing all protocols and adding only HttpSoap12 and Documentation which appears to make matters worse. I then removed all protocols that are not required. The XmlException is gone from the logs but I still get a 400 Bad request :(

I've tested from the local machine (using the hosts file so I can use the correct hostname) to rule out the proxyserver as an issue.

Currrent web.config:

<protocols>
    <!--
        <clear />
        <add name="Documentation" />
        <add name="HttpSoap12" />
    -->
    <remove name="HttpGet" />
    <remove name="HttpPost" />
    <remove name="HttpPostLocalhost" />
    <remove name="HttpSoap" />
</protocols>

Try specifying "AnyHttpSoap" instead of "HttpSoap12".

Or as you said, if they only support 1.2, then instead of adding "HttpSoap12", just remove "HttpSoap" from protocol.

<protocols>
  <remove name="HttpSoap"/>
</protocols>

This might help.

Thanx a bunch for your help.

I've created a small test-website and found that SOAP 1.2 worked with the default configuration. I gaduately added configuration with the goal of mirroring the real config.

Doing this I found that the SOAP extension caused the problem. If anyone experiences the same issues, it is possible to enable the extension for a specific location, but impossible to disable for a specific location.

The resulting (working) configuration is as follows:

<configuration>
    <system.web>
        <webServices>
            <protocols>
                <add name="HttpGet" />
                <add name="HttpPost" />
            </protocols>
        </webServices>
    </system.web>
    <location path="Services/MyOtherWebservice.asmx">
        <system.web>
            <webServices>
                <soapExtensionTypes>
                    <add type="Microsoft.Web.Services2.WebServicesExtension, Microsoft.Web.Services2, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" priority="1" group="0" />
                </soapExtensionTypes>
            </webServices>
        </system.web>
    </location>
</configuration>

Thanks for your much appreciated help!
